The HSE has admitted that some hospitals continue to face challenges in sustaining full staffing complements, as some locum or agency doctors fail to come to work in a dispute over pay.
However, it said that hospital groups were reporting full cover across all sites.
The HSE statement said the Dublin Midlands Hospital Group and the Ireland East Hospital Group continue to be the worst affected by the withdrawal of labour by the locum doctors.
The worst affected sites are Tallaght, Portlaoise, Navan and Letterkenny.
The HSE also said that hospital groups, individual sites and medical recruitment agencies are continuing to work collaboratively to reduce any negative impact on service provision nationally.
Last night the HSE revealed that some agency doctors can earn over €100,000 more than a directly employed HSE doctor.
However, locum doctors do not accrue any pension entitlements and must fund all of their own pensions.
In addition, not all agency doctors would earn a full year's salary at the higher pay rates as some do not get assignments throughout the year.
Even though the HSE has negotiated a new contract with recruitment agencies which reduces the agency rate of pay since last week, agency doctors continue to earn more than HSE employees.
The HSE has now confirmed that in addition to those higher locum pay rates, it also pays agencies a fee ranging from 4-6% of the agency doctor's flat rate of pay.
